In an interview with Fox News Sunday, the Republican presidential candidate doubled down on his assertion that a speech given by President Barack Obama intended to sell the American public on his nuclear deal with Iran contained "coded innuendos employing standard anti-Semitic themes.”

"To act like everything is normal there and that these people are paranoid, I think that's anti-Semitic." Carson added that on a recent trip to Israel, he "couldn't find a single person there who didn't feel that this administration had turned their backs on Israel."

Carson has been given to make bold comparisons in the past, which some have argued are hyperbolic.

But Carson is not the only person invoking the specter of anti-Semitism when describing Obama's Aug. 5 speech at American University. Several conservatives comentators found shades of what they considered anti-Semitism in Obama's speech.
